Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a long-life damping spring for car cushion of multiplicable comfort level, includes cushion 1, rotates on the cushion 1 and is connected with back cushion 2, and the right flank of cushion 1 is provided with the adjust knob 3 that can carry out the angle modulation to back cushion 2, and the left and right sides of back cushion 2 all is provided with side cushion 4, and the inside of cushion 1 is provided with the damping device 9 that a plurality of has multiple shock attenuation effect.

A passenger or a driver sits on the seat cushion 1, and the back cushion 2 provides a leaning position for the user; the adjusting knob 3 can adjust the inclination angle of the back cushion 2, so that a user can conveniently lie down; the side cushion 4 is convenient for the user to lean on the head, arms and other positions.

Further, the front surface of back cushion 2 is provided with a plurality of massage base grain 5, and the top of back cushion 2 is provided with two connecting rods 6, is provided with head back cushion 7 on the connecting rod 6, and cushion 1 is filled with ventilative sponge 8.

The massage base particles 5 are arranged, so that the back of a user can be conveniently massaged; the head rest 7 is arranged so that a user can place the head on the head rest 7; the ventilative sponge 8 of cushion 1 inside packing guarantees the gas permeability, prevents breeding of bacterium.
